Short-term Comparison of Cervical Fusion With Static and Dynamic Plating Using Computerized Motion Analysis

Abstract

Computerized evaluation of digitized films can improve the accuracy and reproducibility of the analysis of anterior cervical fusion. An angular threshold of 2 degrees was selected for this purpose. This study showed that the rate of fusion with a dynamic plate was similar to that of the static plate despite the use of allograft bone with the dynamic plate. In addition, this study found that successful fusions continued to evolve throughout the first year following surgery.
